HARVESTER WEIG HT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 600,665, dated March 15, 1898.

Application filed July 6, 1897. Serial No. 643,561. (No model.)

To all whom it may concern:

Be it known that I, J OSEPH O. V. WISE, a citizen of the United States of America, residing at Oanfield, in the county of Boulder and State of Colorado, have invented certain new and useful Improvements in Harvester \Veight-Equalizers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to a device for equalizing the weight of the binding-table and its attachments of self-binding harvesters when it is moved forward toward the horses to accommodate the table and tying mechanism to short grain; and the object of my invention is to connect the drivers seat in such a manner to the binding-table that when the driver moves the binding-table forward or backward the driver and the seat will be moved with it, but in a reverse direction from that of the table, and the drivers weight will serve to counteract and equalize the weight of the table. In the present state of the art selfbinding harvesters are provided with a binding and tying mechanism which is slidably mounted to the framework of the binder and p is adapted to be moved some six to twelve inches on the frame to accommodate the binding and tying mechanism to properly bind both short and long grain. This table and tying mechanism is very heavy, and when it is moved toward the horses a portion of its weight is thrown on the front of the machine and tongue, and consequently on the horses necks. This bindingtable is arranged so that when in its normal position it is adapted for long grain and in that position substantially balances the machine upon its main driving and carrying wheels; but when the binder is used in a field of grain that contains patches of long and short grain the driver must repeatedly change the position of the bindingtable, and consequently has to intermittently throw on and oft of the horses necks the overbalanced weight of the bindingtable. I obtain this object by the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents a fragmentary perspective View of such parts of a grain-binding harvesting-machine as are necessary to illustrate my invention, and Fig. 2 is a plan view of Fig. l and such parts of a grain-binding machine as are necessary to illustrate my invention.

Similarletters and figures of reference refer to similar parts throughout both views.

Referring to Fig. 1, A and Bdesignate supporting-yokes which form a part of the framework of the binder.

O designates the rear side-board of the binder.

D and E are brackets secured to the endboard C. I

F and G are two rectangular rails. They are secured to the brackets D and E. All binders are provided with these two rails or with a single rail or tube in substantially the same position, and the drivers seat H and its supporting-bar I are secured to them in some convenient manner.

J designates a rail secured to the outside of the yoke-pieces A and B of the frame. To this rail a bracket K is slidably connected by means of the rollers Land the projection M. This bracket supports the outer end of the binding-table M.

O is a rod which extends from the yoke A to yoke B. On this rod is slidably mounted a box P, which is secured to the under side of the table, a portion of which is cut away to show the box more plainly. The table is consequently slidably supported on the rod 0 by this box P and on the rail J by the bracket M. To a suitable projecting part of the box P, I secure a rod Q, which is pivotally connected to the end of a crank-arm R, which is formed on the end of the rod S. The rod S is supported by the bracket T, which is secured to the yoke A. The supporting-bar I of the seat extends to a truck X, which comprises a table portion Y, provided with two upwardprojecting lugs Z, between which the end of the supporting-bar I rests and is secured in any suitable manner to the table portion of the truck. From the table portion two arms 1 and 2 extend downward, and each arm has secured to it at its lower end a roller 3, which rests on top of the rails E, F, and G. These two arms are located at the end of the truck nearest to the seat. At its opposite end of the table portion of the truck two arms 4 and 5 extend down below the rails and have pivoted to them 'rollers 6 and 7, which bear on the lower edge of the rails. The truck is thus secured to the rails against tipping up under the weight of the driver and is perfectly free to be moved along the rails with the seat by any movement in either direction. To the side of the end piece 0 of the frame of the machine I secure the lower end of a segment-shaped casting 8. The rod S passes freely through the center portion of the segment, and at the side of the segment upon the rod S an operating-lever 9 is secured, which is provided with a common form of locking-bolt, which is arranged to engage notches formed in the top of the segment. This lever and segment is arranged on all binders within reach of the drivers seat and a mechanism substantially the same as that portion of the rod S and the crank R, and the rod connecting it with the binding-table is used to move the binding-table on the frame. The chain 16 connects at 18 to the front end of the roller-seat truck and passes around the pulleys 19 and 20. These pulleys are pivots ally supported by brackets 21 and 22, which are secured to the front of the frame of the machine. The pulley 19 is positioned to support the chain between the rails and to hold it outside of the frame, and the pulley 20 is positioned to turn the chain toward the hinding-table, to which it is attached at the point 23. In the chain 16 I place a turnbuckle Z Z, which has threaded connections with suitable 'ends of the chain and which is adapted to keep the chain taut. The chain 17 is secured at 24 to the rear portion of the roller-truck of the seat and passes round the pulleys 25 and 26. These pulleys are pivotally supported in suitable brackets 28 and 27, which are secured to the rear end of the frame in a position to allow each roller to hold the chain outside of the frame of the machine and lead it to the binding-table, to which it is attached at point 29.

The operation of my invention is as follows: When the driver is in the seat and wishes to throw the table forward to accommodate it to small grain, he moves the lever 9 back in the direction of the arrow 10, which movement moves the crank-arm R and the binding-table M forward in the direction of the arrow 11, and the chain 17 draws the seat back in an opposite direction from the movement of the table, and the weight of the table which has been thrown forward on the horses necks by this movement is counterbalanced by the weight of the driver. When the driver reverses the movement of the operating-lever 9 in the direction of the arrow 13, the table is moved back to its normal position and the seat is moved forward to its normal position by the pull on the chain 16. The balance of the machine is thus' always maintained whether the movement of the table in either direction is its full movement or only a portion thereof.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination with the binding-table, of

the rods and crank-arm and the operatinglever connected operatively to it to move it on its supporting-frame, with the drivers seat,

the seat-supportingbar, the parallel bars, the truck mounted on said bars and having its front wheels arranged to bear on the top of said bars, a chain or cable arranged to connect one end of said car with one end of said binding-table, a second chain arranged to connect the opposite end of said car to the opposite end of said binding-table, and suitable supports for said chain or cable, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH o. v. WISE.
